Bait known that I,*'I-IARRIsoN TAYLOR QRoNK, a citizen of the United States, re-

slding in, the city," county, andState of New ,-5..Yor1 hav'e invented-certain "new and use fuli'lmprovements Fluid-Conduits in specification. i l i A Onetype of closet-bowl in general use is provided ,with flushing-rim extending about opposite 'sides thereof toward the front 10f the bowl, which rim' is supplied water through a single rear inlet from 'a supply pipe. Where the 'feed pressure ig; relatively I low the water has sufficient timetddividemore or less equally and each it side of therim" is'sjupplied with its quota of water;'However should the pressure 'ad- *j acent the inlet to the rim be relatively high and-especially where the water is admitted through o'ne of the sides at the rear por tion of the bowl,-'thejten'dency ofthe water Closet-Bowls ofwhic'h the following is a "1s to;continue"in its general direction from 4 Qthe water inlet, pass-the inlet at the near ;-sidefof the rim and about the side or the rim opposite the inlet. -This results in the I 1 fe'edingof a larger volume of water .per

unit of time down one of the sides than is fed down the side adjacent the .water inlet. One'ofthei objects of the invention is'to providea conduit for directing the. flushing water in substantially equalquantities per unit'of time through the pair of openings in aforked passageway; i i

Q, I attain this: bjectbroadly by positionin a :tube in the main iwater passageway, said tube having a loose fit therein and provided 1 }with "a'fclosed end and withthreeopenings inlthe side thereof, the two outside openmgs communicating with "thevtwo openings of the forked. passageways;

tionpf one form of mechanism embodying my lnvention, and the invention also conslsts, in certain new and novel features of construction and combination of parts hereinafter set forth and claimed. Referring to the accompanying drawings: Figure 1 is a plane View of the top of a closet-bowl with portions adjacent the water inlet broken away to show a preferred embodiment of my inventioninstalled in posin-r.

Fig. 2 is a side elevation of the rear portion of the bowl adjacent the water inlet;

Fig. 3 is a side elevation of the tube removed from the bowl; and

Figs. Land 5 are modified forms ofthe tube shown extending into the topand rea sideof the bowl. i

There is illustrated a conventional form of water-closet bowl 1, each side of the seating rim of which is provided with-a flush water conduit 5 both of said conduits onen- --ing from acompartment 6 in the upper portionof the bowl adj acent the rear end thereof. Transversely opposite ends of the compartment are opened to the outside and a tube? inserted through one of the openingsin which position it is fastened by providingone end with a closing cap 8 adapted to bear against the circular shoulder 9 outlining the opening. The opposite end of the tube is threaded and a rubber washer 10 inserted over the threaded end and tightened into engagement with a shoulder 11 by means of a nut 12 disposed between which nut andwasher isa friction ring 13. Theside of the tube is provided with a pair of-spaced apart apertures 14 opening into the conduitsfi. The portion of the tube between these apertures is provided with a relatively small aperture 15 and the adjacent uwall outlining. the compartment is slightly spaced from this small intermediate apertures I sired, the bore of the tube may be con striated in advance at eaehrot the openings to the passageway in the rim by providing apertured plugs 18 for insertion in place.

Instead of inserting the tube transversely into the bowl, the plumbing connections may require that the supply of liquid be introduced preferably through the top or rear side of the bowlinto the compartment 6. In this case the tube may be formed with an annular flange 19 designed to fit against the inner wall of the compartment witha lock nut 20 threaded thereto and having a tight fit with the outer Wall of the bowl about the inlet 21 to the compartment. The tube when inserted into place vertically may have one or more side openings 22 for directing the water into one or both of the conduits 5 and when inserted horizontally through a rear inlet may have the inner end bifurcated to form passageways or nozzles 23 for directing the water to the conduits. V

In operation, the flow of water through the supply pipe is directed to the tube and flows through the two outside apertures leading to the conduits about opposite sides of the rim. Water will also pass through the intermediate aperture to form a ring of water surrounding the tube and tending to separate the compartment into two portions,

so that the water from the end apertures will not pass into the conduits on the opposite side of the bowl. Walls of water will also form in the compartment adjacent opposite ends of the tube so that the flushing streams passing through the .end openings into the conduits will pass through the compartment between more or less fixed walls of water.

Without a device of this characterthe tendency of the water projected through the inlet to the bowl would be to travel about the opposite side of the rim and little or no water would pass directly into the side of the rim adjacent the inlet. With thetube in place as described the flow of water even when under heavy pressure is divided with approximately an equal rate of flow to the two conduits.

It is possible to insert-tubes of different cross-sectional area of bore and with open ings of different size and character to regulate the fiow from the supply pipe to the bowl. In casting the bowls it is practically impossible to insure uniformity of bore in the water conduits and accordingly there is a variation in the supply of water admitted thereto but the tubes herein described may be made of metal, preferably brass, may be made of any desired diameter and can be made to fit the bores cast in the bowl irrespective of their variations from standar dimensions. 7 I

While I have shown and described, and have pointed out in the annexed claims certain novel features of my invention, it will be understood that various omissions, substitutions and changes in the, form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the illvention.

Having thus described my invention, I claim:

1. A closet-bowl having a compartment therein opening through one side of the bowl and a pair of flushing conduits leading from said compartment, a tube insertible into said compartment and provided with a pair of spaced apart apertures leading to said flushing conduits and; means for supplying fluid to said tube.

2. A closet-bowl having a compartment therein openingthrough one side of the bowl and a pair of flushing conduits leading from said compartment, a tube insertible into said compartment and provided with a pair of spaced apart apertures leading to said flushing conduits and means for supplying fluid to said tube,.the portion of said tube between the apertures being spaced from the adjacent wall of the compartment, said portion being provided with an aperture adapted to form a wall of water about the tube between the streams flowing from the first named pair of apertures.

3. A closet-bowl having a transversely disposed passageway in the rear thereof and having a. boreleading from said passageway to a flush fluid outlet, a tube adapted to be positioned in said passageway and having an opening in the side thereof adapted to open to said'bore, means for supplying a flushing fluid to one end of said tube, said tube having-a constriction in the bore thereof positioned between said means and said opening- 4. A closet bowl having a transversely disposed passageway in the rear thereof and having a pair of conduits leading from said passageway to flush fluid outlets, a tube adapted to be positioned in said passageway and having outlets therefrom spaced from but opening directly to said conduits and mians for supplying afiushing fluid to said tu e.

5. A closet bowl having a relatively wide passageway therein and horizontally disposed conduits leading therefrom directly to the interior of the bowl, a'tube extending lengthwise within the passageway and spaced from the conduits and means for sup plying the flushing fluid for the bowl to said tue. V 1

6. A closet bowl having a rim sea-t, flushing conduits extending about opposite sides of said seat, said bowl having a passageway therein constituting an-enlargement of said conduits at their meeting point, a water supply tube provided with three side openings adapted to be inserted into said passageway,
